Builds validation results and evaluates declarative field rules.
Field rules come from field/3 options in a schema block (required, min_length,
max_length, email, matches, min, max, greater_than, less_than). The same rules
are written into the generated TypeScript validators, so the browser rejects what the server
would reject.
A command can add cross-field rules by defining validate/2, returning :ok or
{:error, results} built with error/2.
